[0002] Product packaging refers to the process of externally packaging a product to protect it, facilitate storage and transportation, attract consumers, or enhance the brand image. When the packaging is produced, it needs to be cut again using a cutting mechanism to achieve the desired shape to avoid the packaging being unusable or its aesthetics being reduced due to improper size, and to ensure that it meets strict specifications.

[0003] When cutting product packaging, the existing cutting mechanism first places the product packaging on the upper part of the cutting platform, then fixes the clamping plates on both sides of the outer surface of the packaging, and finally starts the cylinder to move the cutting blade fixed at the output end downward to complete the cutting operation of the packaging.

[0004] Although the existing cutting mechanism can complete the cutting operation of the package, it is not convenient to replace the cutting blade. After the cutting blade is used for a long time, it is worn and needs to be replaced in time. The traditional replacement method requires the operator to manually loosen the bolts that fix the cutting blade and remove the tool. When installing the new cutting blade, it is necessary to realign and tighten the bolts again. This method is cumbersome, time-consuming and labor-intensive, and reduces the cutting efficiency of the package. Summary of the Invention

When cutting, by starting the cylinder 4, the cylinder 4 moves the output end mounting block 6 downward, and the movement of the mounting block 6 brings the internally installed cutting knife 7 to move synchronously, and the movement of the cutting knife 7 can be used to cut After the package cutting is completed, a replacement component is provided on the outside of the mounting block 6. The replacement component is provided to facilitate the replacement of the worn cutting knife 7. A storage plate 20 is provided on the cutting table 1. The storage plate 20 is provided to facilitate the placement of the packaged materials. A fixing component is provided on the storage plate 20. The fixing component is provided to facilitate the fixing of the package. A slider 21 is fixedly connected to the lower right side of the storage plate 20. Telescopic rods 5 are fixedly connected to both sides of the outside of the mounting plate 3. The telescopic ends of the two telescopic rods 5 are fixedly connected to the upper sides of the mounting block 6. The setting of the telescopic rods 5 plays a role in assisting the movement of the mounting block 6. A slide groove 27 is provided on the upper right side of the cutting table 1. The slider 21 is slidably connected to the inside of the slide groove 27. The setting of the slide groove 27 facilitates the movement of the slider 21.

[0028] The replacement assembly includes a U-shaped frame 8, which is fixedly connected to the outside of the mounting block 6. Both sides of the U-shaped frame 8 are fixedly connected to fixed rods 9. One end of the fixed rod 9 is fixed to the U-shaped frame 8, and the other end of the fixed rod is fixed to the mounting plate 6. The two fixed rods 9 are externally slidably connected to a mobile plate 10, that is, the mobile plate 10 slides on the two fixed rods 9. A groove 12 is provided in the middle of the mobile plate 10. A spring 11 is provided on the two fixed rods 9 between the mobile plate 10 and the U-shaped frame 8. The front side of the mobile plate 10 is fixedly connected to an insertion rod 13. The two insertion rods 13 are provided on the two fixed rods. Between the fixed rods 9, first through holes 14 are provided on both sides of the outside of the mounting block 6, and the two insertion rods 13 are slidably connected to the inside of the two first through holes 14. By setting the first through holes 14, it is convenient for the insertion rod 13 to pass through the mounting block 6 and be inserted into the cutting knife 7. Slots 15 are provided on both sides of the inside of the cutting knife 7, and the two insertion rods 13 are plugged into the two slots 15, which improves the stability of the installation of the cutting knife 7. A second through hole 26 is provided on the left side of the upper part of the cutting table 1, and the connecting block 19 is slidably connected to the inside of the second through hole 26. The movement of the connecting block 19 is facilitated by setting the second through hole 26.

[0029] Specifically, when the cutting knife 7 needs to be replaced, first, the operator buckles the groove 12 opened on the movable plate 10 with his hand, grabs the movable plate 10 through this groove 12 and drives it to slide outside the two fixed rods 9. When the movable plate 10 moves, it moves synchronously with the two external fixed rods 13. At this time, the sliding of the movable plate 10 will also apply an extrusion force to the two springs 11 sleeved on the fixed rod 9, causing the springs 11 to deform under the action of external force and compress the length. When the movable plate 10 moves further, the two rods 13 are completely removed from the two slots 15 on the mounting block 6, and the cutting knife 7 is separated from the fixed portion of the mounting block 6. The fixed structure, at this time the operator can easily take out the cutting knife 7 from the inside of the mounting block 6 to complete the disassembly process. When installing a new cutting knife 7, the operator only needs to insert the new cutting knife 7 into the inside of the mounting block 6. Then, loosen the movable plate 10. Under the reaction force of the two springs 11, the movable plate 10 automatically resets, driving the insertion rod 13 to reinsert the slot 15, and firmly fix the cutting knife 7 in the mounting block 6. The entire replacement process does not require additional tools. With the help of the elastic force of the spring 11, automatic reset and stable installation of the tool are achieved. The replacement process is short, the operation time is reduced, and the overall production efficiency of the cutting mechanism is effectively improved.

[0030] Reference Figure 4 and Figure 6 The blanking assembly includes a motor 16, which is fixedly connected to the inside of the cutting table 1. The output end of the motor 16 is fixedly connected to a gear 17. A rack plate 18 is slidably connected to the inside of the cutting table 1. The rack plate 18 is engaged with the gear 17. A connecting block 19 is fixedly connected to the upper part of the rack plate 18. The top of the connecting block 19 is fixedly connected to the lower left side of the storage plate 20.

[0031] The gear 17 is engaged with the rack plate 18, and the gear 17 drives the rack plate 18 to move linearly in a predetermined direction. The rack plate 18 is fixedly connected to the connecting block 19, so that the movement of the rack plate 18 directly drives the connecting block 19 to move in the same direction. The upper part of the connecting block 19 is fixedly connected to the storage plate 20. As the connecting block 19 moves, the storage plate 20 also moves synchronously. The top of the storage plate 20 is used to carry the cut packaging material. Therefore, when the storage plate 20 moves, the cut packaging material is also taken away from the bottom of the cutting knife 7. This series of transmission operations realizes the automatic removal function of the packaging after cutting is completed, and there is no need for the operator to manually remove the packaging. In this way, the contact between the personnel and the tool caused by manual operation is successfully avoided, thereby effectively improving the safety of operation.

[0032] Reference Figure 1 、 Figure 2 and Figure 4 The fixing assembly includes a first fixing plate 22, which is fixedly connected to the upper left side of the storage plate 20. A mounting rod 23 is fixedly connected to the outer right side of the storage plate 20. An electric push rod 24 is fixedly connected to the top of the mounting rod 23, and a second fixing plate 25 is fixedly connected to the output end of the electric push rod 24.

[0033] Specifically, when fixing the package that needs to be cut, first, the package that needs to be cut is placed on the upper part of the storage plate 20, and then the electric push rod 24 is started. The electric push rod 24 moves with the second fixed plate 25 fixed at the output end, so that the package is fixed in the middle of the second fixed plate 25 and the first fixed plate 22. This makes it easy to fix the package that needs to be cut, avoids sliding or displacement of the package during the cutting process, and thus improves the cutting accuracy.

[0034] Working principle: when the cutting knife 7 needs to be replaced, first, hold the groove 12 with your hand to drive the movable plate 10 to move outside the two fixed rods 9, and when the movable plate 10 moves, it moves synchronously with the two plug rods 13 fixed on the external front side. At the same time, the movable plate 10 moves to squeeze the two springs 11 fixed on the external rear side, so that the two springs 11 are deformed under the force. Finally, when the two plug rods 13 are moved out of the two slots 15, the cutting knife 7 can be taken out from the inside of the mounting block 6 for replacement. When installing, insert the new cutting knife 7 into the inside of the mounting block 6, then loosen the movable plate 10, and reset the two plug rods 13 under the reaction force of the two springs 11 to complete the installation of the cutting knife 7, so that the worn cutting knife 7 can be easily replaced. The replacement method is simple and convenient, saves time and effort, and improves cutting efficiency.

[0035] When the cut package is moved from under the cutting knife 7, the motor 16 is started, and the motor 16 rotates the gear 17 fixed at the output end, and the gear 17 rotates to move the externally meshed rack plate 18, and the rack plate 18 moves to move the upper fixed connecting block 19, and the connecting block 19 moves to move the top fixed storage plate 20, and the upper fixed package is moved by moving the storage plate 20. This makes it easy to move the package from under the cutting knife 7 after the package cutting is completed, without the need for the operator to manually move it, avoiding contact between people and the tool, and improving the safety of cutting.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
